Hi,
The below code works for me
NumberFormat threeDForm = NumberFormat.getFormat(#.###);
Thanks and Regards
Gourab.

Hello,
I experience the following - from my point of view unexplainable -
behaviour when using the GWT NumberFormat
(com.google.gwt.i18n.client.NumberFormat). I am using GWT 2.0.3,
Eclipse Ganymed and IE8/FF3.6.
Within my client package I have a static helper class which contains
the following method:
code
public class Utils {
...
public static final NumberFormat DOUBLE2_FORMAT =
NumberFormat.getFormat(##.00);
...
public String formatDouble2(double d) {
return DOUBLE2_FORMAT.format(d);
}
...
}
/code
Using the code above I get a javascript error when using the
formatDouble2 method. Compiling the GWT code in a detailed way and
the javascript error message is something like
com...i18n.client.positivePrefix is null or not an object. The GUI
gets stuck and the application is no longer usable.
So how did I solve it?
During debug instrumentalization I found two ways. Unfortunately I can
not explain either of them - so I was hoping someone can explain me
why it works! ;)
Adding a Window.alert(...) into the formatDouble2 and everything works
fine. Why!?
code
public class Utils {
...
public static final NumberFormat DOUBLE2_FORMAT =
NumberFormat.getFormat(##.00);
...
public String formatDouble2(double d) {
Window.alert(Utils: inside formatDouble2 d= +d);
return DOUBLE2_FORMAT.format(d);
}
...
}
/code
The solution I am currently using is to only use pattern itself as a
static member and create the NumerFormat within the method. This works
too.
code
public class Utils {
...
public static final String DOUBLE2_FORMAT_PATTERN = ##.00;
...
public String formatDouble2(double d) {
return NumberFormat.getFormat(DOUBLE2_FORMAT_PATTERN).format(d);
}
...
}
/code
BTW, changing the public static to private static did not work either.
Thanks in Advance for your help!
Stefan
